To all-whom it may concern:

Be it known that I, Ammo Funnels, a citizen of the United States,residing at Bell River, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements 1n an.

Electric Magnetic Motor, of which the following is a specification. Thisinvention relates to improvements in motors operated motors, andparticularl designed for use motion is adaptable for producing desiredresults.

An object of the invention resides in providing a motor mechanism of thecharacter above mentioned wherein any oscillating member is providedwith a suitable contact mechanism for controlling the energization ofthe solenoid, which solenoid is provided'for controlling a secondcontact mechanism in order that the periodic. operation of the solenoidwill periodically operate the contact mechanism controlled thereby forperiodically energizing an electromagnet adapted to operate theoscillatable member in the periodic energization thereof so thatsuitable means may be operated by or from said member in the operationthereof so as to produce desired movements of mechanism for controllingsigns, advertising matter, or producing mechanical movements of adesired character.

The invention further comprehends the provision of an oscillating memberoperable by theperiodic energization of an electroma et which iscontrolled through the operation of the solenoid which is periodicallyenergized by the operation of the member, which oscillating member isadapted to have suitable connection for producing a periodic rotation ofthe shaft which may be used to operate any suitable mechanicalmechanism.

The invention also comprehen'ds other objects and'improvements in thedetails of construction and arrangement of the parts which are moreparticularly pointed out in the following description and claimsdirected to a preferred form of the invention, being understood howeverthat various changes in the size, shape, and arrangement of parts aswell as the electrical connections between the same may be made with outdeparting from the spirit or scope of the invention as herein set forth.

"The figure illustrates diagrammatically the relation of the parts forthe .control and operation of the oscillating member and other connectedmechanism.

An oscillating member is indicated at 1, mounted at its central portion2 for pivotal An armature 3 is pivotally mounted at 4 on one end of theoscillating member 1 and slidable fits within the core of anelectromagnet 5 which forms the operatmg magnet for the oscillatingmember. At theopposite end of the oscillating ;member 1 is a pawl 6pivotally connected with the end of the oscillating member adapted forcooperation with the ratchet Wheel 7 mounted on the rotary shaft 8, andwhich is prevented from reverse rotation by the spring operated pawl 9.A coil spring 10 normally under compression retains the pawl 6 1noperative engagement with the ratchet wheel 7 at' all times. A coilspring 11 is anchored at one end to the oscillating member 1, and at theopposite end to a suitable stationary support and normally tends to movethe pawl 6 downwardly on the ratchet wheel 7 so that the energization ofthe el'ectromagnet 5 will operate the oscillating member in the oppositedirection. The oscillating member is sloted at 12 longitudinallythereof, and

adjust-ably supports the weight 13 which is adapted to cooperate withthe spring 11 when both a weight and spring are used for producing adownward movement of the end of the oscillating member carrying the pawl6. The slidable adjustment of the weight 13 is adapted to change'thedistance from the pivot 2 so that the period of o eration of theoscillating member can e changed in order that it may be caused tooperate faster or slower, if desired.

It is to be understood however that either a weight or a spring may beused independently if desired.

The oscillating member 1 operates a con- I tact mechanism which includesa movable contact 14 mounted on the oscillating member, and a stationarycontact 15 mounted for cooperation with the movable contact 14. Theoperation of this contact mechanism is such that at the end of thestroke the oscillating member actuated by the electromagnet 5 will causethe contact 14 to engage the contact 15 for operating the hereinafterdescribed structure for deenergizing the electromagnet in order' thatthe weight and spring may operate'to move the same through the oppositestroke of movement for a subsequent operation by the electromagnet. Thiscontact mechanism including the movable and stationary contact 14 and 15respectively controls the solenoid 16, which has a wire connection 17with the stationary contacts, while the movable contact is connected bythe wire 18 to one side of the source of energy supplied through thewires 12) and 20 respectively. The wire 18 is connected to the wire 19from the'source of energy while the wire 20 is connected to a "suitableresistance 21 which in turn has the connection 22 with the otherterminal of the solenoid 16. The circuit with the source of energythrough the wires 19 and 20 is controlled by the switch mechanism 23. Inthis way it will be seen "that the oscillation of the member 1alternately closes and opens the circuit to the solenoid 16.

The solenoid 16 is adapted to operate the armature 24 having a pivotalmounting at 25,'and at the opposite free end provided with the movablecontact 26 .ada ted to engage thestationary contact 27 o a contactmechanism for controlling the energlzation of the electromagnet 5. Oneterminalfof the electromagnet 5 is connected by the wire 28 to thearmature 24 while the stationary contact 27 is provided with the wireconnec- 'tion 29 to the wire 19 from the source of energy. The oppositeterminal of the electromagnet 5 is provided with a wire connectlon 30which may be connected to the wlre 20 from the source of energy througheither the switch 31 or switch 32. The circuit through the electromagnet5 will include the reslstance 21'when the switch 31 is closed, and theswitch 32 is open, so that an electromagnet of relatively smallresistance can be protected' by using the circuit through the resistance21; A coil spring33 connected with the armature 24 normally tends tomove the same to engage the contact 26 with the contact 27 for closingthe circuit to theelectromagnet 5.

Upon the closing of the main control switch 23 for connecting thecircuitsof the apparatus with the wires 19 and 20 from a source of powerit will be seen that the electromagneto will be first energ1zed whichwill operate the armature 3,and draw the same within the magnet, andthereby move the member 1 on the pivot 2 so as to lower the adjacent endof themember, and raise the end carrying the pawl 6 for producing apartial rotation of the shaft 8. At the end of the stroke of themovement of the member 1, the contact 14 will engage the stationarycontact 15 and close the circuit to the solenoid 16 which will draw thearmature toward the core of said solenoid, and move the contact 26 outof engagement with contact 27, and thereby break the circuit to theelectromagnet 5. 'T his deenergization of the electromagnet 5 willpermit the weight 13 and the spring 11 to move the member about thepivot 2 in the opposite direction so as to break the circuit to thesolenoid 16 which will immediately permit, the contact 26 to againengage the contact 27. This will close the circuit to the electromagnet5, and produce a subsequent operation of the oscillating member. In thisway a continued reciprocating movement of the oscillating member 1 onthe pivot 2 will be provided which will produce aperiodic rotation ofthe shaft 8. In this way electric energy is converted into mechanicalmotion through the cooperation of the solenoid and theelectromagnetnnder the control of the oscillating member 1. With adevice of this character suitable mechanism may be operated, such asadvertising signs or other mechanically operated devices in which a stepby step motion is required or desirable. Having thus described theinvention, what I claim asnew is?- 1. An electromagnetic motorcomprising on oscillating member, an electromagnet for operating saidoscillating member, a contact mechanism operated by said oscillatingmember, a solenoid having electrical connection with said contactmechanism for control and periodic energization through operation ofsaid contact mechanism by the oscillation of said member, and a contactmechanism operated and controlled by said solenoid for controllingcircuits with said electro-magnet for periodically energizing saidmagnet alternately with the energization of said solenoid, whereby saidmember may be continuously operated.
